Take inspiration from nature. Create a sustainable world.



Horizom is a regenerative agriculture company that develops the cultivation of giant bamboo on a fair trade model. The objective is twofold: to massively sequester carbon and produce biomass for industry.

Why work with horizon?

  • Pragmatism, integrity and scientific rigor are at the heart of our approach.

    We capitalize on the expertise of our nursery specialist in bamboo as well as on decades of scientific research, mainly produced in Asia where bamboo is an ancient crop.

    We carry out agronomic research activities in our 7 ha nursery located in the Landes, as well as on 10 ha of pilot plantations. We are also working on the recovery of carbon and biomass through industrial partnerships.
